The main objective of this thesis was to determine the influence of tree vigor on susceptibility to Armillaria root disease. First, the effect of thinning, fertilizing and pruning on tree vigor of four young Douglas-fir (Pseudo tsuga menziesii var. menziesi,) plantations was explored. Tree vigor was calculated by measuring wood...
Oregon's rocky intertidal habitats have been subjected to gradually increasing human-use pressures as the coastal and tourist populations have risen over the years. Brosnan and Crumrine (1991,1992) have documented impacts to intertidal communities at Yaquina Head, Sunset Bay, and Haystack Rock that have resulted from people walking on the intertidal...
This report describes current meter measurements from an experiment to measure the deep western boundary current that carries dense water from the Antarctic to the Pacific Ocean. The field measurements were conducted as part of a joint two year experiment by Oregon State University, Texas A&M University, Woods Hole Oceanographic...
Coastal communities in Oregon have experienced dramatic economic and demographic change during the 1980s. Although the timber and fishing sectors are still important, the economies of coastal communities now rely more on non-earned income and tourism. Non-earned income sources, such as transfer payments and investment earnings, account for over forty...

Factors affecting the persistence of mussels (Mytilus californianus) and their associated epibiont species were studied along the central Oregon coast. Interactions between mussels and their algal epibionts (Endocladia
muricata) varied in sign and strength with environmental conditions. In extreme temperatures mussel—epibiont interactions determined survival of individual mussels,
and persistence of...
The development of a Marine Pollution Monitoring Program (MPMP), in any coastal area of the world, requires a precise knowledge of the functioning of the local ecosystem. Because of the differences found in every coastal ecosystem, it is important to recognize and characterize the reservoirs and significant environments that maintain...
The Alaska Coastal Management Program (ACMP) is a networked program, using existing state and local authorities and intended to allow joint state-local management of coastal zone resources and uses. The State of Alaska has outlined broad program goals, and
the local governments were to specify how those goals and additional...
